Label jenis aplikasi dengan auto-detect (Go/AppImage/Electron/Script/Windows/Binary/PWA)

- internal/shortcut/kind.go: deteksi dari isi berkas - build info Go, magic
  AppImage, resources/*.asar untuk Electron, shebang untuk script, MZ untuk .exe
- .exe Windows kini boleh dipasang dan dijalankan lewat wine (Exec=wine <path>);
  kalau wine tidak terpasang, install ditolak dengan pesan jelas
- metadata menyimpan kind; chip jenis ditampilkan di setiap baris shortcut
  (data lama tetap tampil sebagai Executable/PWA)
- dialog menampilkan hasil deteksi setelah berkas dipilih, mis. 'winbox.exe - windows'
- README: bagian label otomatis + screenshot baru
